Analog cellular system of mobile radio communication of AMPS standards.
ANALOG CELLULAR SYSTEM OF MOBILE RADIO COMMUNICATION EMX-2500 BY MOTOROLA FOR AMPS, TAGS, E-TACS, J-TACS STANDARDS
5.1 Structural diagram of the EMX-2500 CCPS
The EMX-2500 is a fully automatic analog cellular radiotelephone system. The system consists of hardware and software components for fixed and mobile communication networks. The structural diagram of the CCTS is shown in Fig. 5.1. The base station is designed for 8 or 16 voice communication channels. It supports 60 degree, 120 degree, and 360 degree antennas. Base stations in cells are connected to each other via base station controllers (BSC) and a switching center (EMH) [5.1].

5.2 Frequency plans of the AMPS, TACS, E-TACS, J-TACS standards SSPS
- ЕМХ-2500 allows the implementation of various communication protocols corresponding to the different SSPS variants [5.1-5.3]:
a) DYNA T.A.S. — based on the AMPS (Advanced Mobile Phf System) standard. It is used in North and South America, as well as in Australia and New Zealand, Asia and the Middle East. An extended band version of E-AMPS is also used, providing an additional number of voice communication channels;
6) TACS, E-TACS (Total Area Coverage System) — used in Europe, Asia, the Middle East and Africa;
в) J-TACS (Japanese TACS) — used in Japan.
The frequency bands occupied by various EMH 2500-based SSPS are shown in Fig. 5.2. Fig. 5.3-5.5 show the frequency plans of the SSPS of the standards under consideration. The distribution of channels in the operating frequency bands is shown in Tables 5.1-5.4. The main characteristics of the AMPS, TACS and E-TACS standards SSPS are given in Table 3.1.
